The component parts include fixation plates such as a C Plate, a N Plate, a J Plate, an I Plate and a K Plate. Two or more fixation plates are configured along an axis, the two or more fixation plates selected from a list, the list comprising a plurality of C Plates; a plurality of N Plates; a plurality of J Plates; and a plurality of I Plates; a plurality of telescoping adjustable struts that connect a first fixation plate along the axis with a second fixation plate of the plurality of fixation plates along the axis, wherein the first and second fixation plates are adjacent plates along the axis; and a plurality of posts, each post connecting two adjacent fixation plates of the plurality of fixation plates along the axis.

FIELD OF DISCLOSURE

The claimed subject matter relates to an external bone fixation systemfor the treatment of bone deformity and trauma.

BACKGROUND OF THE INVENTION

Current External Bone Fixation (EBF) systems for the treatment of bonedeformity and acute trauma employ circular rings that surround apatient's limb. Typically, the diameter of such rings must beapproximately four centimeters (4 cm) larger than the limb being treatedto allow for swelling in the limb. Oversized rings to accommodate largeextremities may also be used. Current systems are both uncomfortable forthe patient and inconvenient when a wound is cleaned. One well-knownreconstructive system is the Ilizarov frame, as shown in U.S. Pat. Nos.4,365,624; 4,615,338; 4,978,348; 5,702,389 and 5,971,984. The Ilizarovframe uses a combination of circular frames, pins and wires fordeformity correction. In addition, current EBF systems for acute traumamay only provide a temporary fix until a definitive treatment isdetermined and they are unstable, difficult to move into a new positionand have minimal or no weight bearing capability.

SUMMARY

Provided is a system for the external fixation of a bone in conjunctionwith the treatment of bone deformity and trauma. The system isapplicable in, but not limited to, both adult and pediatric situations.The system includes a number of fixation plates such as a “C Plate.” a“N Plate,” a “J Plate,” a “K Plate,” an “I Plate” and a “Foot Plate,”which may be arranged in a variety of “single,” “stacked” or “cascade”configurations. The C Plate may be employed to conform to the leg, hipand arm; the N Plate to a leg, arm and foot; the J Plate to the hip andleg; the K Plate to the pelvis and the Foot Plate to the foot. An IPlate may be employed to conform to a patient's foot or to extendportions of the other plates.

Fixation plates are coupled with either posts, rods or telescopingstruts and may include bridges to provide strength and stability. Thedisclosed technology enables ring-like fixation with stable point offixation while leaving an opening to allow for edema and easier accessto the limb under treatment. Different plates may be selected by aHealth Care Provider (HCP) so that the HCP is able to customize anexternal fixation device specifically for a particular patient's anatomyand the patients' treatment. The customized external fixation device istypically attached to a patient's extremity or pelvis by means of acombination of fixation devices such as, but not limited to, wires andpins.

Provided is an apparatus and component parts of a system for theexternal fixation of bones. The component parts include fixation platessuch as a C Plate, a N Plate, a J Plate an I Plate and a K Plate. Thesystem includes a plurality of two or more fixation plates configuredalong an axis, the two or more fixation plates selected from a list, thelist comprising a plurality of C Plates; a plurality of N Plates; aplurality of J Plates; and a plurality of I Plates; a plurality oftelescoping adjustable struts that connect a first fixation plate of theplurality of fixation plates along the axis with a second fixation plateof the plurality of fixation plates along the axis, wherein the firstand second fixation plates are adjacent plates along the axis; and aplurality of posts, each post connecting two adjacent fixation plates ofthe plurality of fixation plates along the axis.

FIG. 7 is an illustration of an telescoping adjustable strut 300 thatmay be employed in conjunction with the claimed subject matter.Adjustable strut 300 is illustrated in two different configurations,i.e., a shortened configuration 302 and an extended position 304. Itshould be under stood that adjustable strut 300 is adjustable to anylength between a shortened configuration and a fully extendedconfiguration. The example is of a “medium” length that may be shortenedto as little as one hundred twenty-five millimeters (125 mm) andextended to a long as two hundred seven millimeters (207 mm).

Threaded rods 306 are attached to the ends of adjustable strut 300.Threaded rods 306 may be extended through holes of plates 100 (FIG. 1).130 (FIG. 2), 160 (FIG. 3), 200 (FIG. 4), 230 (FIG. 5) and 270 (FIG. 6)and fixed with nuts (see 410, FIG. 9) to attach the various plates 100,130, 160, 200, 230 and 270. Swivel joints 308 enable plates 100, 130,160, 200, 230 and 270 to be coupled together in multiple configurationsdepending upon such factors as a patient's size and placement of thedisclosed EBF system on a patient.

Adjustable strut 300 includes an inner sleeve 310 and an outer sleeve312. Outer sleeve 312 fits over inner sleeve 310 and can be positionedto adjust the length of adjustable strut 300. A bolt 314 may be loosenedto adjust the position of inner sleeve 310 and outer sleeve with respectto each other and tightened to secure a particular relative position.

FIG. 8 is an illustration of three hinges and one bolt that may beemployed in conjunction with an external bone fixation (EBF) system toaffix the EBF system to a patient's extremity A male hinge 320 includesa threaded end 322 which is typically inserted through one of the holesof plates 100 (FIG. 1). 130 (FIG. 2), 160 (FIG. 3), 200 (FIG. 4), 230(FIG. 5) and 270 (FIG. 6) and attached to the corresponding plates witha nut (not shown). A hole 324 provides an attachment point for a wire(see 504, FIG. 14), pin (see 506, FIG. 14) or other hardware to affixthe EBF system to a patient's extremity or pelvis.

A female hinge 330 includes a threaded hole 332 that is used to attachhinge 330 to a plate such as plates 100, 130, 160, 200, 230 and 270.Typically a bolt (not shown) would be inserted through one of the holesin the respective plate and threaded and tightened into hole 332. A hole334 provides an attachment point for a wire, pin or other hardware toaffix the EBF system to a patient's extremity or pelvis.

A ninety degree (90°) hinge 340 includes a threaded hole 342 that isused to attach hinge 340 to a plate such as plates 100, 130, 160, 200,230 and 270.

A hole 344 provides an attachment point for a wire, pin orother hardware to affix the EBF system to a patient's extremity orpelvis.

A bolt 350 includes a hole 352 through which a pin (see 528, FIG. 15) orwire (see 530, FIG. 15) may be inserted. When bolt 350 is passed througha hole in one of plates 100, 130, 160, 200, 230 and 270 and a nut (notshown) is tightened, a collar 354 secures the pin or wire into hole 352.

FIG. 9 is an illustration of one embodiment of an external fixationsystem (EFS) 400 in accordance with the disclosed technology thatemploys two N Plates 130 (FIG. 2), two posts 406 and Foot Plate 270(FIG. 6). In a cascade configuration, N Plates 130 are affixed to eachother with posts 402 that are welded or bolted in place. In addition,EBF system 400 includes two (2) Walker Rails 404. Walker Rails 404 maybe attached to Foot Plate 270, providing a cushion or spring interfacebetween EBF system 400 and the ground. In this example, N Plates 130 arecoupled in a “cascade” configuration, which implies that N Plates 130are permanently attached with posts 402 that have been welded orotherwise permanently affixed to N Plates 130. The lower N Plate 130 iscoupled to Foot Plate 270 with adjustable struts 300 (FIG. 7). Posts 406are attached to the front of Foot Plate 270 and Foot Plate 260 isattached to a pair of Walker Rails 404. Posts 406, which provide bothstability to EBF system 400 and additional attachment points for wires(see 504, FIG. 13), pins (see 506, FIG. 13) and other hardware, may bestabilized by a Fore Foot Bridge 408.

Where employed, posts such as posts 402 may be either welded orotherwise permanently attached, i.e., in a pre-configured “cascade”configuration, or bolted, i.e., in a “stacked” configuration, to therespective components. Struts 300 are typically attached to therespective components with nuts such as a nut 410 and swivel joints 308(FIG. 7). In this manner, the various components are able be adjustedinto any of a variety of positions. In addition, struts 300 aretypically configured to be adjustable with respect to the length so thatstruts 300 may be both adjusted for a particular patient and alsoperiodically lengthened during treatment to promote bone growth.

It should be noted,that this particular configuration, like EBF system 480 and unlikeconvention systems with circular rings, would enable the patient to lieon their back without being encumbered by EBF system 500.

FIG. 15 is an illustration of an EBF system 520 with two J Plates 160(FIG. 3), illustrated affixed to a patient's exposed tibia 522 and footbone 524. The patient's leg is not shown in this illustration. J Plates160 are coupled with three telescoping adjustable struts 300 (FIG. 7).Attachments 526, such as hinges 320, 330 and 340 (FIG. 8) and bolt 350(FIG. 8), are employed to attach half pins 528 to lower J Plate 160. Inthis figure bolt 350 is illustrated. For the sake of simplicity, onlyone attachment 526 and pin 528 are labeled. Half pins 528 are thenattached to either a heel bone or foot bone 524. Upper J Plate 160 isaffixed to tibia 522 with half pin 534 and attachment 536, which may beany of hinges 320, 330 and 340 (FIG. 8) and bolt 350 (FIG. 8). A secondpin 538 is attached by means of a hinge 540 to a post 542 that is boltedto upper J Plate 160.

FIG. 16 is an illustration of one embodiment of an EBF system 550 withtwo K Plates 200 (FIG. 4) from a front perspective 552, illustrated inconjunction with a patient's pelvic bone 554 under treatment. Plates200, which may be bolted together, are coupled with three telescopingadjustable struts 300 (FIG. 7). The assembled system 550 is attached topelvic bone 554 by means of pins 556. Pins 556 are coupled to K Plates200 by means of hinges or bolts, which in this example is bolt 350 (FIG.8), only one of which is labeled in FIG. 16 for the sake of simplicity.

FIG. 17 is an illustration of the embodiment of EBF system 550 of FIG.16 from a side perspective 560. Like perspective 552 of FIG. 16,perspective 560 includes pelvic bone 554, K Plate 200, telescopingadjustable strut 300, pins 556 and bolt 350.
